DC's
I cannot recommend the DC highly enough - it ain't the worlds best selling headset for nothing.
You can get them in 2 headband sizes - they do a smaller one for the ladies. I have both sizes. No discomfort reported at all.
I have used all sorts of headsets over the years - some pretty expensive, some 'cheep as chips'.
I also own a variety, Peltor mainly, for my other machines.
However, the DC with cloth earcovers and the gel cushions get my vote.
A quirk of this type of headset - if you suddenly get reports of 'less than fives' reception, check that the microphone is directly facing your mouth. If it is twisted - even slightly - your transmit volume plummets.
Go for the DC.
